>Zero businesses passed on the additional costs onto the consumer? None?

That wasn't the claim made. OP said:

>and businesses absorbed the vast majority of the blow through both stockpiling and taking the bullet.

Which so far as I can tell, is approximately correct, even if the "vast majority" part is suspect. A goldman sacs from last year estimated consumers will pay 55% of the tariffs by end of 2025. However that only includes the tariffs paid, whereas OP also included "stockpiling".
